NIAG - Neutron Imaging and Applied Materials
NIAG is a group within the Laboratory for Neutron Scattering and Imaging LNS , in the division research with Neutrons and Muons NUM of PSI. NIAG is operating 2 dedicated neutron imaging facilities and the neutron strain scanner (diffractometer) POLDI for users from scientific institutions and industry. Neutron radiography is complementary to X-ray radiography due to differences in radiation matter interaction. Neutrons interact with the atomic nucleus, whereas X-rays as electromagnetic radiation rather interact with the electrons. For strain scanning this also enables access deep into the bulk of engineering materials and geological samples. NIAG also provides complementary x-ray imaging (in-situ bi-modal) and has dedicated beamtimes for imaging studies at the testbeamline BOA providing an intense cold polarized neutron beam.
